I'm a DSLR video hobbyist and wanted to motorize this 7ft slider I built with Rig Wheels http://www.rigwheels.com/ and box track.

I used the Arduino mega and motor shield from radio shack, along with a potentiometer and switch to control the speed and direction of the servo. I modified the servo to rotate continuously by removing the control board and plastic tab on the gear that makes it stop.

To my knowledge, external control of the GH2 (like the Canon implimentation) is not possible. The most you can do is play with an external shutter release setup. This is of-course, the last time I checked up on it when I read about the way Canon's can be controlled with, I think a Nintendo DS with custom software.

I bought two remote shutter releases, I think its Pixco brand from China. Works well. The one I actually want to use for long exposures, although I can see myself modifying it into a nice, custom enclosure which will also house the intervalometer.

I haven't done anything of the sort yet. What I can tell you is that there are three plates in the unit, first two touch and you get the "half-press" function, those two touch the third and you get shutter release. There's two resistors, and if I remember correctly, the one resistor goes between the first two plates, and the second resistor between the second two.

Wish I can tell you more but I have too much on my plate at the moment to focus on that. Hope you get some info regarding. I hope to finally get to this in the next two to three months. I am also thinking of a pan-tilt head with slider. Though I want my pan-tilt head to have the added function of being controller real-time via a joystick of sorts, like a turret gun

Hey- just am starting to get involved in open source motion control and time lapse (I am not a big video guy so i will mostly do Time Lapse stuff) I saw your project over on the OpenMoco forum- looks really good so far!! I am trying at the moment to create a very inexpensive (<$200) portable, pan/tilt timelaspe head (gotta do what you can when you are a high school student ). I noticed that you were based in Idaho- I live in southern Idaho so maybe we are not that far apart

the possibility to talk with the camera Firmware via USB or Remote would be great.Im thinking about the IR port or the Wireless interface in some Brands.

Idea 1It sould be possible to access the shutter, appartue or any-settings in some canon DSLRs with a modification of the Magic Lantern Firmware.Its open source too.mybeee this one:http://arduino.cc/forum/index.php?action=printpage;topic=125318.0

Idea 2 is to put a USB-Sniffer between a Camera and A computer with tethered Software like Lightroom and get the code. Maybe its crypted with some Security algorytm like Timestamps to protect it from Manufactures for 3.Party products...

you can bring your slider to the next level If its possible .Just some daydreamings...I Dont know... lets see... lets try....
